Orange Oil & Termites

Over the years, pest control experts have researched natural termite control methods as alternatives or supplements to traditional treatment. Orange oil is one product that has shown limited success in controlling targeted, active drywood termite infestations.

Orange Oil Termite Extermination
Orange oil products have been used with varying degrees of success to control drywood termite infestations. Orange oil contains d-limonene, an extract from orange peels. It has a very high citric acid content, which dries out a termite’s exoskeleton.

When used to treat termite infestations, orange oil is injected into the wood where drywood termites live. The termites that have direct contact with the d-limonene or that eat wood treated with the d-limonene will dry out and die from lack of moisture.

Limitations of Orange Oil for Termite Control
Orange oil products will control drywood termites that come into direct contact with the products. However, orange oil products do not have some of the advantages of more common termite control products. Orange oil products do not leave a residue, so effectiveness is limited to termites that come into contact with the materials in a couple of days. Other control products that can be shared among drywood termites (non-repellent termiticides) or that are inhaled (fumigants) are more effective because they are more likely to reach all of the termites in a colony.

Orange oil treatment works best for very small drywood termite infestations where your pest control expert can clearly define the boundaries of the infestation to fully treat the affected area. He or she can evaluate an infestation by size and location to judge the potential effectiveness of orange oil treatment or other treatment methods.
